My first few days with the nexus have been plagued with what seems like network lock ups or connectivity dropping but further investigation has revealed problems with the Synology DS13Air wireless capability.
To be fair sitting at my desk the wireless connect ion is perfect and much faster than my old net gear wpn802, however, that is about 2 feet from the router. Moving downstairs results in less than 20mbps connections and frequent loss of connect ion.
My net gear wireless signal works fine downstairs - I have raised a support ticket with Synology and as a result have changed the connect ion type from hotspot to wireless router. Functionality remains seemingly unchanged but connectivity is not improved.
Worse, I have been experimenting with dlna / upnp functionality and am having problems in that the media server on the ds 213 disappears at random. Much experimentation has resulted in the discovery that when I connect wirelessly using the, flawed, synology wireless I lose access to the synology media server but it works fine on rge net gear. So another bug on which I am still awaiting a response from synology.
